## Description

From the Manufacturer The Cisco SPA 508G 8-line IP Phone provides small businesses a rich user experience with a monochrome backlit display for ease of use, aesthetics, and on-screen applications; HD voice for unsurpassed voice clarity; enhanced full duplex speaker phone for clear conversations across the desk; and an integrated switch port to connect your computer. Comprehensive Series of Phones Cisco offers small business customers an extensive portfolio of phones. Being the global leader in voice over IP and Unified Communications, Cisco recognizes that you need options to make sure you have the right phone for the right workspace, employee, or job. In certain situations aesthetics are important, whereas in other situations durability, size, the number of buttons, or features are more important. No matter what your business needs are, the Cisco SPA 500 Series IP Phones have a product that will meet those needs while making your employees’ jobs easier. Cisco SPA 500 Series IP Phones Part of the Cisco Small Business Pro Family, the Cisco SPA 500 Series IP Phones are specifically designed for small businesses and are supported on all of the Cisco small business phone systems. The Cisco SPA 500 Series is a portfolio of affordably priced, reliable, stylish, easy-to-use phones for small businesses that need a smaller-size, Wi-Fi connected desk top phone, and Bluetooth. The SPA 500 Series IP phones consist of: Cisco SPA 501G 8-line IP PhoneCisco SPA 502G 1-line IP PhoneCisco SPA 504G 4-line IP PhoneCisco SPA 508G 8-line IP PhoneCisco SPA 509G 12-line IP Phone with Programmable KeysCisco SPA 525G 5-line IP Phone with Color Display HD Voice You will receive increased voice clarity when pairing the Cisco SPA 508G with the Cisco Smart Business Communications System or an HD voice-compatible hosted phone service. With HD voice, the audible range of produced sounds is significantly greater than traditional phones. The Cisco SPA 508G provides an HD-capable speaker phone and handset for accurate delivery of voice sound that helps reduce fatigue on long calls and eases the experience for those frequently on the phone during the day. HD voice can also help make conference calls more productive by enabling participants to clearly hear and understand others on the call. Easy to Use The SPA 508G was designed to be used and operated with minimal end-user training. The phone has several lighted indicators that let users know when there is a message waiting for them, an extension is in use, a coworker is on the phone, or if they are on headset, speakerphone, or mute. Below the backlight monochrome screen are four buttons that control digitally displayed soft keys. To reduce confusion and the need for additional buttons on the phone, these keys offer access to features that change based on the state of the phone: if you're on a call, off a call, on hold, or dialing, for example. There are also eight backlit buttons that can be used for speed dials, shared lines, or other functions. Dedicated buttons for voicemail, hold, and phone settings provide easy access to common features. Integrated Ethernet Switch Ports The SPA 508G provides you with two switch ports that allow you to connect both your phone and computer to your network using a single Ethernet cable. When you plug your SPA 508G into any data jack on the network, the phone will maintain its profile, speed dials, and user settings. This eliminates the need for a technician if you need to shuffle equipment around. And by having the phone and the computer on the same cable, you will reduce your cost to add new users by minimizing the need for multiple cable drops.

Review: Top quality VoIP phone with black and white screen. - Top quality VoIP phone with black and white screen. I use it in the SIP mode. Easy to setup and upgrade firmware. Easy to use web interface (unlike previous versions of Cisco SIP phones). Please be sure to read firmware upgrade instructions: firmware must be upgraded to an intermediate version first before being upgraded to the latest version. Excellent audio quality on both speaker phone and handset. Excellent price. I recommend getting this 8-line phone as you can use unused line buttons as speed-dials. An 8-line phone is only a few dollars more than a lesser-line phone in the SPA-5xx series.
Review: Works nicely for me. - The review that gave this phone 1 star because of the PoE issue wasn't reasonable. To be clear - the phone does not come with a power adapter. You will need to buy one separately or use a PoE (Power over Ethernet) injector or switch to power the phone. I don't mind this at all - in some locations, it's easier to power it with PoE, and I appreciate not having to pay for an extra adapter I won't use. This is not a consumer phone. Don't buy it expecting to plug it in and start making/receiving calls without some work to configure it to talk to a service provider. I bought several to use with an Asterisk system and I've been very happy with them. They're easy to configure via the web interface (which takes a long time and has a lot of options) or they can be made to download a (lightly) XML-structured configuration file, which is very helpful if you've got more than one to configure/manage. They support the G.722 codec for "high def" voice, if the entire call path + other endpoint support it too. If you've played with the Sipura phones/ATA's, this will feel familiar, though the build quality of the hardware is much nicer than the Sipura 841's. I bought two as evaluation units and have ended up buying several more, and I expect there's another batch order coming in the future since the last ones have worked nicely. The only downside - and it's not a big deal, because I don't use the "switch port" - is that the downstream network jack loses connectivity if the phone reboots.

## Questions & Answers

**Q: What is the least expensive way to power this phone?  Anyone have a specific product recommendation for power adapter?  Thanks.**
A: I used these: Phihong PSAC05R-050(P)-RI got them from www.mouser.com.  You have to buy the plug prongs separately from the adapter, but they aren't that expensive.

**Q: Can I plug 5 magicjack GO's into this phone?**
A: No, you can't.  This is a VoIP phone -- it's not intended to be tunnelled through this kind of device.  Your device is meant for a regular phone.

**Q: Does this phone have Wi-Fi built in?  It seems to mention it above but I wanted to be sure.**
A: No, not this model.  You'll need to get the spa525 series for built in WIFI

**Q: Does this come with a power supply or not?**
A: We include the power supply
